Reset free count properly in rtems_rfs_bitmap_map_clear_all().

In rtems_rfs_bitmap_map_clear_all(), control->free is set to 'elements',
which is the number of elements in the bitmap. This is incorrect, as
control->free should contain the number of free bits, not elements.

This change fixes the logic and resets control->free to a correct value.
